SIPP vs Workplace Pension

Introduction

A Self-Invested Personal Pension (SIPP) and a workplace pension are both UK-registered pensions designed to help individuals save for retirement. While they operate under the same broad pension legislation, they are established in different ways and offer different structural features.

Workplace pensions are arranged through employers, whereas SIPPs are arranged directly by individuals. Understanding the differences between these two pension types helps explain how contributions are made, how investments are selected, and how each pension is administered.

This guide explains the structural differences between SIPPs and workplace pensions without expressing a preference for either.

What Is a Workplace Pension?

A workplace pension is a pension scheme set up by an employer. Under UK automatic enrolment rules, most employers are required to enrol eligible employees into a workplace pension scheme.

Key features typically include:

• contributions from both employer and employee
• investment into a default fund or selected options
• administration handled through payroll

Most modern workplace pensions are defined contribution arrangements.

What Is a SIPP?

A SIPP is a type of personal pension arranged by an individual rather than an employer. It is registered under UK pension legislation and operates as a defined contribution pension.

A SIPP allows pension savings to be invested in a wider range of permitted investments than some standard workplace pensions.

How SIPPs and Workplace Pensions Are Similar

Despite being set up differently, SIPPs and workplace pensions share several core features.

Both:

• are UK-registered pensions
• operate under the same access age rules
• are subject to contribution allowances
• are governed by UK pension and tax legislation

Neither structure removes pension rules or guarantees outcomes.

Key Structural Differences

How They Are Set Up

• Workplace pension: arranged by an employer
• SIPP: arranged directly by the individual

This difference affects how contributions are made and how the pension is administered.

Contributions

In a workplace pension:

• contributions are usually deducted from pay
• employers typically contribute alongside employees

In a SIPP:

• contributions are paid directly by the individual or employer
• payroll is not required

Contribution limits apply equally to both.

Investment Choice

Workplace pensions often:

• invest contributions into a default fund
• offer a limited selection of alternative funds

SIPPs typically:

• allow access to a broader range of permitted investments
• provide more direct investment selection within provider rules

Investment access depends on provider policy as well as legislation.

Administration and Control

Workplace pensions:

• are administered largely by the employer and provider
• involve minimal decision-making by employees

SIPPs:

• require more direct involvement in investment selection
• involve separate administration and custody structures

Both are administered by regulated pension providers.

Charges

Charge structures can differ.

Workplace pensions often:

• bundle charges into a single annual fee
• operate within charge caps for default funds

SIPPs may:

• separate platform charges from investment charges
• apply dealing or custody fees depending on investments held

Portability and Employment Changes

Workplace pensions are linked to employment. When employment changes:

• contributions usually stop
• the pension remains invested

A SIPP is not linked to employment and continues regardless of job changes.

This structural difference affects how pensions are managed over a working lifetime.

Accessing Benefits

Both SIPPs and workplace pensions follow the same access rules.

At the time of writing:

• benefits are generally accessible from age 55
• this is scheduled to increase to 57 from April 2028

Benefits can be taken in similar ways, subject to pension rules.

Common Misunderstandings

“Workplace pensions are always better funded”

Funding depends on contribution levels, not structure alone.

“SIPPs replace workplace pensions”

They are different arrangements and can coexist.

“Workplace pensions have no investment risk”

Both are defined contribution pensions with investment risk.

“SIPPs are only for advanced investors”

SIPPs are a structural pension type, not a skill classification.

Summary

A SIPP and a workplace pension are both UK-registered defined contribution pensions. They operate under the same pension rules but differ in how they are set up, how contributions are made, how investments are selected, and how they are administered.

Understanding these structural differences helps explain how different pension arrangements operate within the UK system.
